A type of variation that involves 3 or more quantities that may vary directly.

• Direct Variation

• Inverse Variation

• Joint Variation

• Combined Variation

This type of variation states that the two quantities increase at the same time or decrease at the same time.

• Direct Variation

• Inverse Variation

• Joint Variation

• Combined Variation

The cost c varies directly as the number of n pencils is written as

• c = kn

• k = cn

• n = k/c

• c = k/n
